I had a Bac S specializing in mathematics with Very Good and I know how complex math is and a misunderstood chapter can handicap the student for the rest of the program. I will help you understand the course, assimilate it and know how to apply it in the exercises. I did an HEC preparation and thus am used to writing and speaking both English and Spanish. I will be able to communicate the essential points of grammar as well as work on specific themes in order to deepen both the English and Spanish language and culture.
